Embodiment 1

[0041] like Figure 1 to Figure 3 As shown, this embodiment provides a polymorphic data storage system for an electric power information system, which includes:

[0042] The data conversion module is used to read the file data in binary form and convert it into a large binary file (BBF, Big Binary File). The BBF data slice is divided into several small data slices, and each small data slice may be of a different size. Wherein, the length L of the small data fragment is determined according to the maximum multiplexing rate. According to the length L of the small data slice, a small data slice (SDS, Small Data Slice) of length L is divided. Store SDS using distributed cloud storage. For each stored SDS, calculate the HASH value, length and storage address of the slice, and generate Small Data Slice Information (SDSI, Small Data Slice Information) accordingly. The function of the data conversion module is that since the power grid business system involves polymorphic data suc...

Embodiment 2

[0053] Embodiment 2, corresponding to Embodiment 1, this embodiment provides a method for storing polymorphic data in an electric power information system, including the following steps:

[0054] (1) For polymorphic data, it is uniformly read in binary form and converted into a large binary file (BBF, BigBinary File). The BBF is divided into data slices, and each slice can be of a different size. The length L of the slice is determined according to the maximum multiplexing rate. According to the length L of the slice, a data slice (SDS, Small Data Slice) of length L is divided. Store SDS using distributed cloud storage. For each stored SDS, the HASH value, length and storage address of the slice are calculated to generate Small Data Slice Information (SDSI, Small Data Slice Information) information.

[0055] (2) Small data fragmentation storage. Store SDS using distributed cloud storage, calculate HASH value, length and storage address for each stored SDS, and generate sma...

Embodiment 3

[0060] This embodiment provides a computer device, including a memory, a processor, and a computer program stored in the memory and operable on the processor. Wherein, when the processor executes the computer program, the steps of the method for storing polymorphic data in the electric power information system in the second embodiment are realized.

Abstract

The invention discloses an electric power information system polymorphic data storage system and storage method. The method comprises the steps of: taking a polymorphic data file as a large binary file, carrying out the slicing, storing the sliced data to a cloud server, generating data slicing information description, generating a file abstract based on the slicing information, and storing the file abstract in a block chain. Therefore, under-chain storage of the data ontology and on-chain storage of data element information are realized, the polymorphic data processing complexity of an electric power information system is simplified, and the high efficiency, the real-time performance and the safety of data storage and transmission are improved.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to the technical field of data storage. Background technique [0002] With the continuous deepening of the informatization process of the power information system, more and more data types are involved in the power business system, and the total amount of data is getting larger and larger. A variety of heterogeneous data has brought a series of problems to the data sharing and efficient transfer of power information systems. At this stage, the purely centralized data sharing model is increasingly difficult to meet the needs of safe, credible and efficient data sharing and storage. [0003] Existing storage methods mainly include centralized storage and blockchain storage: [0004] 1. Defects of centralized storage [0005] Centralized storage is the simplest data storage strategy. The polymorphic data of the traditional power grid business system adopts centralized stora...
